TaskTHIS is up and running again. Sorry for the downtime, but since I host it for you guys for free, I don't think you can complain too much. :-)
In the process, it's moved URLs as well. You can now find it at:
The old URL (taskthis.darthapo.com) should redirect you there automatically.
I had to convert TaskTHIS from Rails 1.1 to Rails 2.1, which was not too fun. Especially since it had already been converted from pre-1.0 to 1.1.
Anyway, it's probably still a little rough around the edges, so if you find any bugs please add a post in the support forum.
